      "value": "The General Options plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.1.0. This is due to the use of sanitize_text_field() for output escaping in the Contact Number (ad_contact_number) field — a function that strips HTML tags but does not encode double-quote characters to their HTML entity equivalent ("). When the stored value is echoed inside a double-quoted HTML attribute (value=\"...\"), an attacker-supplied double-quote character breaks out of the attribute context. Even with WordPress's wp_magic_quotes mechanism (which prefixes quotes with a backslash), the resulting \\\" sequence is NOT treated as an escaped quote by HTML parsers — the backslash is rendered as a literal character and the bare double-quote still closes the attribute. This makes it possible for authenticated attackers with Administrator-level access and above to inject arbitrary web scripts in the admin settings page that will execute whenever any administrator visits the General Options settings page."

      "value": "El plugin General Options para WordPress es vulnerable a Cross-Site Scripting Almacenado en versiones hasta la 1.1.0 inclusive. Esto se debe al uso de sanitize_text_field() para el escape de salida en el campo Número de Contacto (ad_contact_number) - una función que elimina las etiquetas HTML pero no codifica los caracteres de comillas dobles a su equivalente de entidad HTML (\"). Cuando el valor almacenado se imprime dentro de un atributo HTML entre comillas dobles (value='...'), un carácter de comillas dobles proporcionado por el atacante sale del contexto del atributo. Incluso con el mecanismo wp_magic_quotes de WordPress (que antepone una barra invertida a las comillas), la secuencia resultante \\\" NO es tratada como una comilla escapada por los analizadores HTML - la barra invertida se renderiza como un carácter literal y la comilla doble sin escapar aún cierra el atributo. Esto hace posible que atacantes autenticados con acceso de nivel de Administrador o superior inyecten scripts web arbitrarios en la página de configuración de administración que se ejecutarán cada vez que cualquier administrador visite la página de configuración de General Options."
